Embodiment Construction

[0054] The above content has fully described in detail the technical solution claimed by the present invention, and the present invention will be further described below in conjunction with the accompanying drawings. The mobile intelligent terminal used to implement the present invention is realized under the iOS platform of Apple Inc. Based on the client-server (client-server) architecture, it includes two main parts: the mobile client based on the iOS platform and the server based on the Microsoft Windows platform. On the server side, Windows Server is written with the programming language C#, which is mainly responsible for session management, algorithm call of digital makeup based on sample templates, and database management. On the client side based on the iOS platform, the mobile application program is written with the programming language Objective-C, which is responsible for image collection, data transmission and user interaction.

Abstract

The invention provides a facial image layer decomposition method based on an improved guide filter, and the method comprises the steps: carries out the improved guide filtering of a facial image brightness channel, obtaining a human face structure information layer, further carrying out differential operation, and obtaining a texture detail layer. According to the invention, the method carries out the regularization factor adaptive adjustment optimization of a guide filter and Gaussian blurring and corrosion processing of a parameter matrix image, and obtains different filtering effects of a facial image in different regions. The method is used for a digital makeup system, obtains an excellent layer decomposition effect, and remarkably reduces the time complexity of layer decomposition.

Description

technical field [0001] The invention belongs to the technical field of image processing and artificial intelligence, and in particular relates to a human face image layer decomposition method with an improved guided filter for digital makeup applications. Background technique [0002] With the popularization of digital photos and the rapid development of computer technology and image processing technology, using image processing technology to digitally make up facial images has become a hot research issue. At the same time, digital makeup technology has great application potential in daily life. Cosmetics e-commerce uses digital makeup to provide customers with a virtual trial function. Makeup service agencies use digital makeup to provide customers with the best makeup solutions. People use digital makeup to choose their own makeup in daily life. Own photo makeup and more. [0003] At present, there are few literatures on digital face makeup technology. In the paper "Res...
